This invention relates to improvements in atomizing devices for use -in laundering`to meisten clothes about to be ironed and has for its object to provide a simple and ellicient device of this character which is easily retillable with water and which will discharge the water in the form of a very'fine, almost vaporlike spray.

In the accompanying drawings illustrat- 'ing this invention Fig. 1 is a side elevation, partly broken away, of a spraying or atomizing device constructed in accordance with my invention.

Fig. 2 is a fragmentary central vertical section of the same. y

l4` ig. 3 is a detail section of the same on the line 3 3 of Fig. 2.

Fig. 4 is an inverted plan view of the removable cap element of the device.

F ig. 5 is a plan view of the body portion of the portion of the device which consti tutes a closure element for the bulb.

The device of my invention includes a receptacle l for water or other liquid which may be of the collapsible type such as a rubber bulb, manually operable to supply compressed a-ir, or may consist of a metallic vessel suitably connected with a source of supply of compressed air, the rubber bulb being here illustrated as preferred.

Mounted in the mouth portion of the re ceptacle 1 is a head 2 of cast metal which is tapered at its lower end portion 3 and is equipped with the external bead 4 for engaging the annular shoulder at the inner end of the mouth or neck portion of said receptacle which, in the instance illustrated, consists of a conventional type of rubber bulb or bottle. In the event that said head 2 is to be mounted on a different type of receptacle, the lower end portion thereof 'may obviously/'be modified accordingly.

In the upper end portion 'of the head 2 I provide a foraminous or skeleton partition wall 5 which carries an axially disposed tube 6 projecting some distance above and below the said wall. To the lower or inner endportion of the said tube 6 there is attached, in the instant case, a piece of flex- -ible tubing 7 which may bend or flex as the bulb 1 is inclined to extend below the surface of contained liquid so as to permit a large part thereof to be discharged before relling becomes necessary.

That portion of the head 2 above the partition wall 5 is internally threaded to receive the externally threaded lower end portlon of the cap member 8. The latter is of generally cylindrical form and is provided with a central bore 9 adapted to snugly recelve the upper end portion of the tube 6 andvwhich terminates in a small port of passage 10 connecting the bore 9 with the lateral discharge duct 11 between the ends of the latter, said port or passage 1() being angularly disposed to both the bore 9 and duct 11 and leads toward the discharge end of the latter. At said discharge end I provide a small detachable nozzle 12.

At its inner end the duct 11 communicates via the small port 13 with a bore or air passage 14 which is parallel with the bore 9.

At one side of the bore 9 is a passage 15 which extends through the'cap member 8 and is of smaller diameter at its upper or outer end than at its inner end to provide a valve seat 16 upon which the check-valve 17 seats, the latter being trapped in the lower end portion of said passage or port 15 by striking projections 18 from the wall of the mouth thereof to-prevent the said valve from dropping out.

The operation of the device is as follows:

.To partially fill the bulb 1 with water or other liquid, the cap member 8 is removed, the bulb 1 partially collapsed and so maintained while said bulb is inverted and its mouth portion disposed below the level of the liquid contained in another receptacle, whereupon the bulb is permitted to expand vand thus draw in water.' The supply of the latter may also be obtained from a faucet underneath which the bulb is held in upright position. I

The cap member 8 is now replaced and then, upon forcibly contracting the bulb 1, the air contained in said bulb will be compressed and will throw the check-valve 17 to the seat 16 and, at the same time, will cause liquid to flow through the tube 6 and port 10 into discharge duct 11 and thus into the path of air projected into the inner end of said duct 11 through the port' 13. The air-jet so delivered will impinge upon and break up or atomize the water flowing from the port 10, this vaporlike liquid admixed with air being projected from the nozzle 12. Upon releasing pressure on the bulb, the latter will expand thus causing the cheek valve to leave its seat and drawing in a fresh charge of air.

I claim as my invention: A 1. A device ofthe kind specified comprising a receptacle having a discharge opening at the top thereof, a foraminous member mounted in said o ening, an axial tube carried by said mem er and extending at one cud to a point near the bottom of the receptacle, a closure cap for said member provided with a lateral discharge duct, a central passage in said cap detachably connecting with the other end of said tube and communicating with said discharge duct between the ends of the latter, an air passage in said cap communicating at its discharge end `with the inner end of said discharge duct, and a check-valve controlled air intake port in said cap.

2. A device of the kind specified comprising a receptacle having a dischargeiopening at the top thereof, a foraminous member mounted in said opening, an axial tube carried by said member and extending at one end to a point near the bottom of the receptacle, a closure cap for said member provided with a lateral discharge duct, a central assage in said c ap detachably connecting with the other end of said tube, a minute port connecting the said central passage with said discharge port between the ends of the latter, and angularly disposed relatively to said passage and said duct, an air passage in said cap communicating at its discharge end With the inner end of said discharge duct, and a check-valve controlled air intake port in said cap.

3. A device of the kind specied comprising a collapsible receptacle, a oraminous member mounted in said opening, an axial tube carried by said member and extending at one end to a point near the bottom of ythe receptacle, a closure cap for said member provided With a lateral discharge duct, a central passage in said cap detachably connecting with the other end of said tube, a minute port connecting the said central passage with said discharge port between the ends of the latter, and angularly disposed relatively to said passage and said duct, an air passage in said cap communicating at its dischargeend with the inner end'of said discharge duct, and a check-valve controlled air intake port in said cap, said air passage being connected with said discharge duct through a port of smaller diameter .than

the latter.
